摘 要: “互联网+”能否对制造业高质量发展产生明显的促进作用,是我们理解“互联网+”战略的重要切入点和落脚点。基于2002—2016年中国省级层面的面板数据,在系统分析“互联网+”对中国制造业发展质量的影响机制基础上,运用投影寻踪法、OLS、工具变量法等多种方法实证检验了“互联网+”对中国制造业发展质量的影响效应。研究结果表明:“互联网+”能够对中国制造业发展质量的提升产生显著的促进效应,这一结论十分稳健;“互联网+”对中国制造业发展质量的影响存在明显的区域异质性,“互联网+”对中西部地区制造业发展质量的提升作用更为明显;对长江经济带样本进行进一步研究,表明相较于其他地区,“互联网+”是长江经济带地区制造业发展质量的重要支撑。 |

Abstract: Whether “Internet+” can significantly promote the high-quality development of manufacturing industry is an important entry point and foothold to understand the “Internet+” strategy. Based on the Chinese provincial panel data from 2002 to 2016 and on the systematic analysis of the influence mechanism of “Internet+” on the development quality of China's manufacturing industry, this paper empirically tested the influence of “Internet+” on the development quality of China's manufacturing industry by using projection pursuit method, OLS method, instrumental variable method and other methods. The results show that “Internet+” can significantly improve the development quality of China's manufacturing industry, which is a very stable conclusion. The influence of “Internet+” on the development quality of China's manufacturing industry has obvious regional heterogeneity, and the effect of “Internet+” on the improvement of the development quality of manufacturing industry in central and western regions of China is more obvious. Further research on the samples of the Yangtze River Economic Belt shows that compared with other regions, “Internet+” is an important support for the development quality of the manufacturing industry in the Yangtze River Economic Belt. |
